  • I’d argue that parents are different to a ‘leader’ as we perceive them, or as I read was suggested in the comment. Children will stick with their parents, up to the point at which they’re ready to start their own family, like you say, but is that leadership in the same sense?

    But yes, I agree, pack = family is accurate.


  • Dogs don’t need a leader - the whole alpha male wolf thing has long been disproven, by the original author none the less. Dogs are highly social and live in groups, yes, but there’s no boss dog. Very few animals have a concept of a leader. In fact I’d argue that none do and it’s a totally human idea.

    I like your cat/dog thinking idea though. Cats very much think ‘me me me’!



  • Maybe if there was a public transport system still running that was not just a cash cow and stifled for the benefit of big oil then it wouldn’t matter who used it when.

    Some people wake very early and may only be well enough during rush hour to travel… and yet they’re not supported in doing so, even though it’d cost relative pennies.

    Oh and re your last Q, disabled people aren’t allowed to go out on the lash or to the theatre etc, they’re disabled so should be tucked up in bed staring at the samecwall they’ve been staring at all daytime. It saves the government tens of pounds a year that!

    PS I’m not being narky at you, rather the system.






  • https://www.newscientist.com/article/2489578-gold-can-be-heated-to-14-times-its-melting-point-without-melting/

    “White and his team fired a powerful laser at a 50-nanometre thick sheet of gold for 45 quadrillionths of a second…”

    As a rank amateur I don’t understand the other discussions here, but my thinking is that if a material is heated up for such a short period of time, and also only in a very small location (“The laser was focused to a spot approximately 100 µm in radius”), not across the whole mass, then the energy will dissipate across the mass of the material without building up enough to break the bonds and melt.

    For me, what’d be more significant to know is how long it’d take for melting to occur/what’s the tipping point.

    So I’ve skimmed through the journal article and:

    https://www.nature.com/articles/s41586-025-09253-y

    “Notably, the temperatures exceed the proposed limit of 3Tm in both cases for over 2 ps. This time is approximately an order of magnitude longer than the characteristic phonon oscillation period and, thus, much longer than required for homogeneous melting”

    So the gold did melt, just not instantaneously!

    “Our experimental findings raise an important question about the ultimate stability limit for superheating.”

    Right so both news articles avoid stating that melting occured so far as to suggest it didn’t and that was what was significant…oh well, reading the journal article was interesting at least!

    One question of mine I didn’t see was answered is, what significance do the xrays have on the temperature and time taken to melting?

    I had to look this up as it sounded unusual, but looking at the younh plant it is basically a small trunk covered in long floppy pine leaves/needles that superficially looks like a clump of grass at first. I suspect there’s no evolutionary advantage to looking like grass, but storing up energy before growing upwards makes sense if there’s a periodic fire risk with each fire risk period being over a couple of years. Also handy for dealing with browsing pressure from particulary hungry critters following a fire.






  • There’s tonnes of blackthorn and a lot of sheep in the UK and I’ve never heard it to be problematic. Sheep ate pretty dim, but bramble is definitely not thorny/spiney enough to get caught bar the odd occasion. I’m sure I heard about a shrub (African maybe) that sheep can get completely ensnared in and die, but can’t find it!
